Definitions

• this invention relates to a nematode repellent composition
• a nematode repellent composition comprising an effective nematode repellent amount of a fatty acid and an anthranilate ester.
• this invention relates to a method of repelling nematodes employing such composition.
• Plant parasitic nematodes cause billions of dollars of damage each year to agronomic crops, vegetables, fruits, flowering trees and shrubs. Almost all major plant species are susceptible to infection by these pests, which typically affect the roots of host plants but also can damage above-ground parts including the stem, leaves and flowers. Nematodes of particular concern include those belonging to the genera Meloidogyne (root knot), Heterodera (cyst), Globodera (cyst), Pratylenchus and Xiphinema.
• Anthranilate esters such as methyl anthranilate and dimethyl anthranilate have long been known to be useful as bird repellents.
• U.S. Pat. No. 2,967,128 describes the use of such compounds to deter both domestic and wild birds from eating seeds, berries, grains, fruits and the like.
• a formulation of dimethyl anthranilate has been commercialized as the product BIRDSHIELDTM.
• this bird repellent composition comprises an anthranilate ester and an alkyl metal salt of a fatty acid; rather than a fatty acid in acid form. According to this publication, the addition of such fatty acid salts results in the formation of micelles of such anthranilate compounds, permitting a more even distribution of such compounds on the surface treated and enhancing their efficacy as bird repellents.
• anthranilate esters have been identified as being insect attractants—for example, U.S. Pat. No. 5,296,226 (Askham) states (at Column 3, lines 20-23) that “insects are readily attracted to dimethyl and methyl anthanilate. Crops relatively free of insects were quickly reinfested after being treated with either material.” This finding is supported by the disclosures in U.S. Pat. No. 6,958,146 (Askham et al), U.S. Pat. No. 7,867,479 (Dunham et al) and U.S. Pat. No.
• the present invention is directed to a composition comprising an effective nematode repellant amount of a composition comprising: (a) an anthranilate ester; and (b) a fatty acid.
• this invention is directed to a method of repelling nematodes employing such composition.
• the present invention is directed to a composition comprising an effective nematode repellant amount of a composition comprising: (a) an anthranilate ester; and (b) a fatty acid.
• anthranilate esters which may be employed include those compounds described in U.S. Pat. No. 2,967,128, which publication is hereby incorporated by reference, and include dimethyl anthranilate, methyl anthranilate, ethyl anthranilate, phenylethyl anthranilate and menthyl anthranilate.
• Preferred anthranilate esters are dimethyl anthranilate and methyl anthranilate, with methyl anthranilate being particularly preferred.
• the fatty acids which may be employed as component (b) include saturated and unsaturated fatty acids containing from 8 to 24 carbon atoms, with fatty acids containing from 13 to 21 carbon atoms being preferred.
• Illustrative of the fatty acids which may be employed are oleic acid, ricinoleic acid, linoleic acid palmitic acid and stearic acid; with oleic acid being particularly preferred.
• the fatty acids may be employed in the form of their salts or esters. When employed as salts, the use of postassium and/or sodium salts is typically preferred.
• Esters which may be employed include C 1 -C 5 alkyl esters, with ethyl esters being particularly preferred.
• the weight ratio of fatty acid to anthranilate ester employed in the compositions of the present invention range from 1:10 to 20:1.
• such ratio will range from 1:5 to 10:1; more preferably such ratio is from 1:1 to 5:1.
• compositions of this invention may further comprise additional additives conventionally employed in agricultural applications.
• additional additives conventionally employed in agricultural applications.
• further components which may be included in the compositions of this invention are antioxidant agents which serve to substantially prolong the desirable action of the fatty acid.
• antioxidant agent(s) protect the chemical and physical integrity of the fatty acid against reaction with oxygen and air pollution alone or in the presence of light.
• suitable antioxidants including commercial and specialty chemicals and their combinations, mixtures and proprietary compositions that are well known to those educated in the art.
• One particular antioxidant agent is ascorbic acid palmitate.
• the amount of the antioxidant is preferably from 0.001-0.1% by weight of the total composition.
